I bought my Gravity 560 at a few weeks ago and I am so impressed with this grill.  It is very well built and looks like it will last for years.  It is also really easy to use - Fill the hopper, light a starter, set your temp and you are ready to cook within minutes.  The cooking area is also plentiful. My first cook for 6 people was cedar plank salmon, baked potatoes and grilled veggies.  I had plenty of space to cook everything at the same time with room to spare.  Overall I am very pleased with my purchase, the only negative is the iPhone app that needs some work. Thankfully you don't really need the app to cook amazing food on it.
